Firefox 29 and Push to kindle

So I have the Push to kindle icon up in the FF toolbar. The upgrade does not even show a Push to Kindle icon among the toolbar options.

I can switch to the keyboard shortcut, but would have preferred the icon.

Hi Philip, I upgraded to Firefox 29 and the icon remained in the toolbar. If yours was removed, can you see if it appears when you right click the toolbar and click ‘Customise’?
